35-70 Gbyte SPARCstorage DLT7000 Tape Drive Manual—February 1997
Installation
1
This chapter describes how to install, configure, and troubleshoot the DLT7000
tape drive.
Installing the Tape Drive
1. Determine your operating system using the uname -rs command.
!
Caution – For SunOS 5.5 or 5.5.1 operating systems, you must perform the
procedures in Appendix A, “Modifying the st.conf File," before proceeding.
2. Shut down the operating system.
Use either the init or shutdown command. See the man pages for these
commands or the Solaris AnswerBook online documentation.
3. Find an available SCSI device identifier (SCSI ID) for the tape drive.
To check for an available SCSI ID, enter probe-scsi-all at the ok
prompt. Use a SCSI ID that is not returned by this command. Tape drives
are usually set to a SCSI ID of 4 or 5. Write down the SCSI ID (and SCSI host
adapter identifier) for future use.
Note – Do not choose SCSI ID 7; it is reserved for the host adapter.
4. Turn off the power to your system and then to your peripherals.
1
1
5. Prepare your system or enclosure for servicing.
Follow the procedures in the service manual for your system or enclosure.
6. Install the tape drive.
Refer to the procedures in your system or enclosure service manual. Install
this drive as you would any full-height device.
a. Connect the SCSI and power cables to the connectors on the back of
the tape drive (Figure 1-1).

b. Set the SCSI ID.
For systems or enclosures with a SCSI ID cable, install the SCSI ID cable
as shown in Figure 1-2 and set the SCSI ID for the tape drive using the
SCSI ID switch on the system or enclosure.

7. Power on your peripherals and then your system.
Note – If your system starts to reboot, interrupt the reboot process by
pressing the Stop and A keys together.
8. Reboot your system using the boot -r command.
9. Load a tape cartridge into the tape drive (see “Loading a Tape Cartridge”
on page 13).
Wait for the tape drive to fully load the tape cartridge.
Note – If all of the LEDs on the right or left side of the tape drive front panel
are blinking, then the tape drive has failed its power-on self-test (POST). Go to
“Troubleshooting” on page 6.
10. Determine which remote number the tape drive has been mapped to.
a. Process the remote numbers in the /dev/rmt directory.
# ls -l /dev/rmt/? | sed 's/.*rmt\///'
For example, a system with two tape drives (one connected to an internal
SCSI host adapter and one to an external host adapter) might return:
# ls -l /dev/rmt/? | sed 's/.*rmt\///'
0 -> ../../devices/iommu@f,e0000000/sbus@f,e0001000/dma@f,81000/esp@f,80000/st@4,0:
1 -> ../../devices/iommu@f,e0000000/sbus@f,e0001000/QLGC,isp@2,10000/st@5,0:
Remote number
SCSI host adapter
SCSI ID
b. Find the remote number that contains the controller and SCSI ID (st)
number for the tape drive you installed.
In the previous example, the remote number 0 would be used for a tape
drive connected to SCSI ID 4 on SCSI host adapter at
dma@f,81000/esp@f,80000.

11. Verify that the system recognizes the tape drive.
#mt -f /dev/rmt/remote_number status
•
A correct response would resemble:
#mt -f /dev/rmt/3 status
Other tape drive:
sense key(0x0)= No Additional Sense
file no= 0
block no= 0
#
residual= 0
retries= 0
Other tape drive on the first line of the output indicates that the tape
drive is correctly recognized. The rest of the output does not matter.
•
Incorrect responses include:
• No tape loaded or drive offline indicates there is no cartridge
in the drive or that the cartridge is not yet loaded. Install a cartridge or
wait for the cartridge load to complete and retry the mt status
command.
• No such file or directory indicates there is no tape drive
attached to that rmt (remote) number. Try another remote number.
• SCSI tape drive indicates the st.conf entry is incorrect. You must
edit the st.conf file and reboot until you no longer see SCSI tape
drive.
The Tape In Use LED should be lit, signifying that the drive is ready for use.
Go to Chapter 2, “Operation".
Note – If the tape drive does not complete POST, or if the right or left side
LEDs blink repeatedly, go to “Troubleshooting” on page 6.

Troubleshooting
If the DLT7000 tape drive fails during POST or operation, use Table 1-1 to
determine the problem and the action to take.
Table 1-1
6
Troubleshooting
Symptom:
Your system does not recognize the DLT7000 tape drive.
Action:
Make sure that:
• The SCSI ID is unique.
• The SCSI data cable is not loose.
• The SCSI bus is correctly terminated.
• You have rebooted the system using the boot -r command.
Symptom:
All LEDs on the right- or left-side of the tape drive front panel
blink.
Action:
Try to unload the tape and reinitialize the drive by pressing the
Unload button, or turn the drive power off and then on again.
The right or left side LEDs stop blinking and the drive tries to
reinitialize. The LEDs should turn on steady again and go off if
the test succeeds.
If all right or left side LEDs still blink, the drive has a hardware
failure.

1. Assumes a typical compression ratio of 2:1. The compression ratio will vary depending upon the type of
data being compressed.
Write-Protect
The tape cartridge has a write-protect switch (Figure 2-2) to prevent accidental
erasure of data. This switch can be set prior to or after inserting the tape
cartridge into the tape drive.
•
To write protect a tape cartridge, move the switch to the left so that a small
rectangle is visible.
•
To write enable a tape cartridge, move the switch to the right so that the
rectangle is not visible.
If the write-protect switch is changed while the tape cartridge is being written
to by the tape drive, the change does not take effect until the current write
operation completes.

Handling and Storage
!
Caution – Do not drop or bang the tape cartridge. This can displace the tape
leader, making the tape cartridge unusable and possibly damaging the drive.
Follow these guidelines when handling tape cartridges:
•
Do not forcibly remove a tape cartridge from the drive. If a cartridge is
difficult to remove, reinsert the tape cartridge, wait for the tape cartridge to
load, and then try to unload the tape cartridge again.
•
Do not use adhesive labels on the tape cartridge. Use only the labels that fit
into the tape cartridge label area. Using other labels may cause the tape
cartridge to jam in the tape drive.
•
Do not move a DLT7000 tape drive with a tape cartridge loaded; doing so
can damage the tape cartridge.
When not in use, return a tape cartridge to the plastic enclosure it was shipped
in and store it in a clean, dust-free environment. In addition:
•
Store tape cartridges in temperatures between 20˚C and 30˚C (68˚F to 86˚F).
For longer tape cartridge life, store it at a stable temperature and as close
22˚C (72˚F) as possible.
•
Store tape cartridges where the relative humidity is between 30% and 50%.
For longer tape cartridge life, store it at a stable relative humidity and as
close to 40% relative humidity as possible.
•
Keep tape cartridges out of direct sunlight and away from heaters and other
heat sources.
•
Keep tape cartridges away from electromagnetic interference sources, such
as terminals, motors, and video or X-ray equipment. Data on the tape can be
altered.
Note – If a tape cartridge has been exposed to extreme heat or cold, stabilize
the cartridge at room temperature for the same amount of time it was exposed
(up to 24 hours).

Selecting Density
You can select the density that the tape cartridge will record data by using the
front-panel Select button or by using a software command. In either case, the
new density does not take effect until a write from beginning of tape (BOT) is
executed. Until then, the original density will be used.
Note – Blank tape cartridges do not have default densities. The DLT7000 will
not light any LEDs on the left-side of the front panel until data has been
written to the tape.
Valid Densities
Table 2-4 shows the densities that can be selected for the DLT7000 tape drive.

Selecting Density Using the Front Panel
To select density using the front panel:
1. Load the tape cartridge into the tape drive.
The Tape in Use LED blinks while the tape loads. After the tape is loaded,
the Tape in Use LED remains lit. The LEDs on the left side of the drive light
to show the tape cartridge’s prerecorded density.
2. Press the Select button until the LED(s) showing the desired density light.
The original density LED(s) will go out. The selected density LED(s) will be
on steady and the Density Override LED will blink. Then the selected
density will blink and the LED(s) for the original density and the Density
Override LED will be steady.
3. When a write from BOT occurs, the selected density will be used.
The selected density and the Density Override LEDs are on steady.

Using a Cleaning Tape Cartridge
!
Caution – Use only a DLT Type III cleaning cartridge to clean the
tape drive.
When the Use Cleaning Tape LED lights:
1. Load cleaning tape cartridge into the tape drive. See “Loading a Tape
Cartridge".
Note – If the Use Cleaning Tape LED lights after you load the cleaning tape
cartridge, cleaning has not been done because the cleaning tape cartridge is
expired. Replace the cleaning tape cartridge. A cleaning tape usually lasts
about 20 cleanings.
2. Wait for the cleaning process to complete.
The Tape In Use LED stops blinking. The beeper sounds and the Operate
Handle LED lights.
3. Unload the cleaning tape cartridge. See “Unloading a Tape Cartridge".
4. Record the date of the cleaning on the cartridge label.
Note – If a data cartridge causes the Use Cleaning Tape LED to blink or the
Use Cleaning Tape LED still lights after you clean the drive head, then the data
cartridge may be damaged. Try another data tape cartridge. If the second tape
cartridge works, then backup your original tape cartridge onto another tape
cartridge. Discard the old tape cartridge.
System Diagnostic Support
SunVTS™ 1.0 diagnostic software, which was distributed with the Solaris 2.5
software environment, requires that you apply patch number 103097-01 to your
system. SunVTS 2.0 diagnostic software and later versions do not require a
patch. You can obtain any needed patches through your normal service
channels.
This tape drive is not supported by the SunDiag™ diagnostic software.

Modifying the st.conf File
A
The Solaris software environment recognizes all tape drives and autoloaders
that were supported by Sun when your operating system was released. If your
system uses SunOS releases 5.5 or 5.5.1, which were released before the
DLT7000 tape drive, you need to modify the /kernel/drv/st.conf file so
that your Solaris software will recognize the DLT7000 tape drive.
If you are familiar with this procedure, go to “Modifying the st.conf File” on
page 22. For more information on this procedure, go to “Understanding the
st.conf File” on page 20.
19
A
Understanding the st.conf File
The beginning of the st.conf file contains possible values that you might use
to configure third-party or other unsupported tape drives. These values are
divided into three sections:
•
•
•
tape-config-list
Tape device identifiers
Configuration values
tape-config-list
The line:
#tape-config-list=
indicates the start of values that the operating system will use to configure
previously unsupported tape devices.
Note – There can only be one active (uncommented) tape-config-list=
line in the st.conf file.
Tape Device Identifiers
The next section, which includes lines like:
#
#
"ARCHIVE Python 28454","Archive Python 4mm Helical Scan","ARCH_Python",
"ARCHIVE Python 29279", "Archive Python 4mm DAT Stacker","ARCH_Python",
and ends with a line like:
#
"\076\000",
1
"Fujitsu 1/2\" Cartridge",
"Fujitsu_half";
2
contains:
20
35-70 Gbyte SPARCstorage DLT7000 Tape Drive Manual—February 1997
3
A
1. The information about the tape device that the operating system sees when
it 'looks at' a tape device.
2. The information the operating system outputs when queried about the tape
device (by programs such as SunVTS diagnostic software).
3. A string which acts as a pointer to values that will be used to configure the
tape device.
Note – The first two lines of the example end in commas. The last line in the
example ends with a semi-colon. You must follow this format when adding
multiple tape devices to the st.conf file.
Configuration Values
The third section contains the values that will be used to configure the tape
devices. It has lines like:
#ARCH_Python
=
1,0x2c,0,0xde39,4,0x00,0x8c,0x8c,0x8c,3;
The part of the line before the equal sign (=) is the string that is linked to the
values that will be used to configure a tape device. The second part of the line
contains the configuration values. These values are well defined in the st man
page.
If you look at the first two examples in the Tape Device Identifiers section, you
will see that both the ARCHIVE Python 28454 and the ARCHIVE Python
29279 lines end with the string ARCH_Python. This means that the operating
system will configure both tape devices according to the parameters set in the
ARCH_Python line.
Note – Each line in the configuration section must start with a unique string.
Also, each line in this section ends in a semi-colon(;).
Modifying the st.conf File
21
A
Modifying the st.conf File
Read this entire procedure before editing the st.conf file.
Note – The syntax is critical. Verify the placement of commas, semicolons, and
beginning and ending quotation marks.
1. Become superuser.
% su
Password:
#
2. Make a copy of the original st.conf file as a backup (st.conf.old).
#cp /kernel/drv/st.conf /kernel/drv/st.conf.old
3. Edit the st.conf file.
Using an editor, scroll through the st.conf file to the following line:
#tape-config-list=
a. Delete the # character that begins the line, if it hasn't already been
removed.
b. Using the editor, continue to scroll until you come to the end of the
“Tape Device Identifiers” section.
The line will look something like:
#
"\076\000","Fujitsu 1/2\" Cartridge", "Fujitsu_half";
c. On the next line, add the following entry exactly as shown:
“SUN
DLT7000”, “Quantum DLT 7000”, “QDLT7”;
5 spaces

Note – If multiple devices are enabled (lines uncommented) only the last
uncommented line with this format must end with a semicolon. All previous
lines with this format must end with a comma.
d. Using the editor, continue to scroll until you come to the end of the
“Configuration Values” section.
The line will look something like:
#WtQIC =
1,0x32,512,0x0624,1,0x00,0;
e. On the next line, add the following entry exactly as shown:
QDLT7 = 1,0x36,0,0x1D639,4,0x82,0x83,0x84,0x85,2;
Note – All lines in this section end with semicolons.
f. Save and exit the file.
